Efficient punched skeleton processing

Strips of foils or sheets are punched out in the thermoforming process, especially for packaging products (cups, blister packs, boxes, etc). The thermoplastic punch skeleton waste arising here is re-processed by the new “RST Thermoform” granulator into re-usable regrind material. RST Thermoform granulators are fitted with special feeding equipment that can be provided in optional vertical or horizontal versions. Punched skeleton feeding into the granulator hopper takes place with frequency or dancer arm control, whereby the intake is adjusted according to the feed rate of the production machine, so that fluctuations are compensated.

The machines are equipped with a stiff torsion-resistant rotor, in open

or closed design, that is produced from one solid piece of metal.
